LAMP-TURNING MECHANISM.

Be it known that L-NELSON citizen of the. United States, residing at Malone, in the county of I-Iilland State of Texas, have invented certain new and-useful Improvements. in Lamp-Turning Mecha- IllSIHSfOf which the follo vmg s a specificainvention relates to new and improved mechanismyfor angula-rly' ad ustmg one of the lamps of an automobile, said mechanism being adapted to be operated from thedrivers seat. Thus the driver of an automobile is enabled from his seat to direct one of the forward lamps'in any direction withina certainarc so that the lamp may be caused to i'ollow the curve of the road or to illuminate any ob ect at the sidei'of the road 'or street as desired.

I haveillustrated an exemplification of my nventlon 1n the accompanying drawing, in WhlCll- Figure 1 is a. perspective View oftlie in vention applied to the correlated parts of an.

automobile. Fig-f2 is a transverse section of v the lamp mounting.

Referring more particularlyto the drawing, reference character 1 designates l the chassis rail, of any standard automobile, on which, in 'the present instance, one of the forward lamps is mounted. A11 angular bracket member is fixed on the chassisrail l by the bolt aud nut 3 or in'a'n'y desired manner. The bracket member 2 is'providedl with a centrally-disposed aperture 4:, in which is mounted a vertical bearing post 5.

Thepost 5 is provided with a circular base 6 adjacentthe bracket 2.. A sleeve 7, provided with a lower radial extension 8, is rotatably mounted on the post 5. The pre sentiug faces of the parts 6 and 8 are pro-.

for the reception of thepost 5, as clearlyshown in Fig. 1 preferably provide, a

washer 11 between-the bracket 10 and the sleeve 7 and a retaining'nut m is'screwed' onto the upper threaded end or the post 5. The extension 8 is provided wither radial Patented Feb. 1'3, rose Application filed December. 5, 1912." Serial No. 735 050.

flange andthe lamp bracket 10 is fixed to rotate with the sleeve 7, by a bolt and nut 1 1 mounted in corresponding apertures in the flange 13 and bracket 10. The lamp 15 is mounted onthe arms of the bracket 10 in any convenient manner.

I have shown a' mechanism, for rotating the lamp from the drivers seat on the swivel mounting just described. The bracket 10 has fixed t0 the arms thereof a rigid longitudinal cross-piece 16. An extensible lever arm comprising the two members 17, -18 isse'cured to the cross piece at one side thereof. lhe

meeting en'ds of'the members-17, 18 are tele' scoped together, the-ends being" bcnt at-19 t0 respectively grip the adjacent arm and the telescoping portions being corre'sp0nd-' ingly slotted. By means of a bolt andnut 20 passing through the slots the length of the lever arm may be adjusted to accord with the particular car to which the devfce affixed. A hand lever 21 is pivotally secured to the free end of the member 17 and is ful-.

crumed at 22 on the chassis rail 1. The lever 21 is provided Witht'he usual quadrant and hand-operated dog for retaining the lever in the desired adjusted position. It is obvious'that when the lever.21 is thrown forwardly or rearWardly'of-its middle position the lamp is swung to the right or left respectivelyfthe degree of deflectiondependthe road as the car turns, 01', on a straight road, to pick out any obj ect at thefside of the road. Also, for city use, in passing along a straight street, one lamp remains straight inn on the angular'displacement of the lever.
